Another thing I miss in calculators is an ENG mode working like this:

Usual ENG ----- "alpha" ENG
123.456e12 ---- 123T456
123.456e9 ----- 123G456
123.456e6 ----- 123M456
123.456e3 ----- 123k456
123.456e0 ----- 123.456
123.456e-3 ---- 123m456
123.456e-6 ---- 123u456
123.456e-9 ---- 123n456
123.456e-12 --- 123p456
123.456e-15 --- 123f456 (not a!!)

Does anybody know of a calculator working this way?

RPL calculators (HP 48/49/50) can emulate CASIO's ENG key: https://groups.google.com/forum/#!topic/...d03tImdu-w

ex.

real numbers
0.01 'ENG\->' 10.E-3 'ENG\->' 10000.E-6 'ENG\->' 10000000.E-9 'ENG\->' 10000000000.E-12
0.01 'ENG\<-' 10.E-3 'ENG\<-' .01E0 'ENG\<-' .00001E3 'ENG\<-' .00000001E6 'ENG\<-' .00000000001E9

5000.E-3 'NORM' --> 5. (STD format)

real numbers with unit
'1_m' 'U\->' '1000._mm' 'U\->' '1000000._\Gmm' ('\Gm' = 'μ' = micro)
'1_m' 'U\<-' '.001_km' 'U\<-' '.000001_Mm' ('k' = kilo, 'M' = mega)

useful programs for units:
